Unusual cause for smoldering dysphagia

A 30-year-old black woman presented with heartburn and odynophagia. She had a 2-year history of Behçet’s disease and systemic lupus erythematosus and had been treated with colchicine, hydroxychloroquine, and sucralfate. Odynophagia was not related to the presence of oral ulcers as they were painless and when they were in remission the patient would still intermittently complain of substernal pain. The patient underwent upper digestive endoscopy that revealed only small mucosal irregularities in the upper third of the esophagus. Biopsies of these segments showed marked acanthosis and papillomatosis of the squamous epithelium as well as intense lymphoplasmacytic infiltrate with an increased number of intraepithelial lymphocytes (IEL). There were neither granulocytes nor signs of viral infection. The endoscopic findings were then attributed to regenerative changes of the epithelium and the patient was started on a proton pump inhibitor (PPI), assuming gastroesophageal reflux disease (GERD). During the following years there were flare-ups of rheumatologic disease activity due to the patient’s lack of adherence to therapy. However, there was no correlation of the patient’s maintained (although scarce) complaints of transitory dysphagia and substernal pain.

Controlo da tuberculose em Portugal : papel e qualidade da detecção de casos

RESUMO - A impressionante evolução da incidência notificada desde 1950 evidencia o quanto o sistema de informação é sensível ao esforço de notificação, reflectindo ainda o impacte das medidas de controlo que foram sendo introduzidas, bem como alguma melhoria nas condições sociais com efeito favorável sobre a doença (Briz, 2005). Sendo a tuberculose uma doença de notificação obrigatória, nos termos da Portaria n.º 766/86, de 26 de Dezembro, os casos deverão ser sempre comunicados à Autoridade de Saúde, em impresso aprovado. O facto de a tuberculose ter um sistema de informação próprio tem permitido um conhecimento relativamente completo da situação epidemiológica. (DGS, 1995) Pretende-se caracterizar o perfil de distribuição da incidência notificada da tuberculose pulmonar, em Portugal Continental, nomeadamente a nível distrital, no período compreendido entre 2000 e 2008, inclusive, partindo-se depois para um estudo mais pormenorizado, relacionado com a sensibilidade do sistema de notificação da tuberculose, no sentido de se quantificarem os problemas de subnotificação. Para validação da notificação, serão utilizados os dados de 2007 e 2008. Procurar-se-á depois obter o perfil da incidência ajustada para a detecção em cada um desses anos, avançando-se de seguida para a identificação e caracterização de parâmetros complementares e de acesso fácil que contribuam para interpretar a distribuição geográfica da incidência notificada, em função da sua provável validade. Perante o eventual confronto com o problema da subnotificação, a identificação das razões da menor adesão à notificação de casos de tuberculose pulmonar apresenta-se quase como inevitável, sendo feita através do recurso a entrevistas a informadores-chave. --------------------------------------ABSTRACT - The impressive development of the incidence reported since 1950 shows how the system is sensitive to the effort of notification, still reflects the impact of control measures have been introduced, and some improvement in social conditions with favorable effect on the disease ( Briz, 2005). As tuberculosis a notifiable disease, according to Ordinance No. 766/86, December 26, cases should be reported to the Health Authority, approved in print. The fact that tuberculosis have an information system itself has allowed a relatively complete knowledge of the epidemiological situation. (DGS, 1995) The aim is to characterize the distribution profile of the reported incidence of pulmonary tuberculosis, in Portugal, particularly at district level in the period between 2000 and 2008, starting from then to a more detailed study, related to the sensitivity of the system notification of tuberculosis, in order to quantify the problems of underreporting. For validation of the notification, we used the data from 2007 and 2008. Search will then obtain the profile of the adjusted incidence for detection in each of those years, advancing is then for the identification and characterization of additional parameters and easy access to contribute to interpret the geographical distribution of reported incidence in according to their likely validity. Given the eventual confrontation with the problem of underreporting, the identification of reasons for the lower adherence to reporting cases of pulmonary tuberculosis has become almost as inevitable, being made through the use of interviews with key informants.

Estudo sobre o insight em pessoas com psicose

Para além das variáveis clínicas e sociodemográficas existem concerteza importantes componentes individuais que desempenham um contributo importante no nível de insight apresentado por cada pessoa doente, por exemplo, o nível de inteligência, personalidade, cultura, experiências passadas, memória, etc. A natureza clínica, emocional e/ou intelectual do termo ajuda-nos a compreender a complexidade da dificuldade que existe na sua tradução e, inclusive, na sua compreensão. Daí que as definições atribuídas ao conceito sejam muito distintas e variem consoante a formação teórica do autor/investigador. Pretende-se, a partir dessa identificação/compreensão, promover a qualidade de vida destas pessoas através do desenvolvimento de novas aprendizagens que possibilitem uma cooperação activa. É igualmente fundamental ir ao encontro das capacidade intactas de maneira a possibilitar a aquisição de novos(s) comportamento(s) que tenham um impacte positivo nas queixas, sinais, sintomas, incapacidade e disfuncionalidade apresentados pelo/a utente. Uma vez que a própria conceptualização do termo traduzirá aquilo que se pretende avaliar,será efectuada uma reflexão detalhada acerca dos instrumentos e definições que têm sido mais utilizadas para explorar o insight nas psicoses.Procurei, no meu trabalho de investigação, realçar e promover a importância que cada sujeito, alvo de intervenção, desempenha ao longo do seu processo de recuperação e na prevenção de recaídas. No seguimento dos objectivos acima descritos, para além da revisão teórica efectuada ao fenómeno em termos de conceptualização e estudos desenvolvidos na área de investigação, foi,neste estudo, realizada a contribuição para a validação do instrumento “Assessment of Insight in Psychosis: a re-standartization of a New Scale” de Marková & Berrios (2003).O fenómeno de insight escolhido pela Insight Scale, relata menos as mudanças vividas em relação à doença mental, e mais a actual consciência e articulação de tais mudanças. Tendo como base uma abordagem psicopedagógica, o fenómeno do insight aqui explorado assentou numa perspectiva reabilitativa, actual e multidimensional, que fosse para além das dimensões clínicas tradicionais. Neste sentido é apresentada uma escala original, intitulada “Escala de Avaliação do Insight e Identificação das Necessidades em Pessoas com Psicose”, bem como um modelo de intervenção psicopedagógico breve, assente nos pressupostos descritos ao longo do trabalho.-----------------------------------------ABSTRACT: The importance of insight in people with mental illnesses was first studied in psychiatry, in the first decades of the 20th century, by people as important as Lewis (1934) and Jaspers (1959). However, this field of investigation was left unexplored for many years. Only in the last decade has this phenomenon become the object of numerous scientific investigations, having been given special attention by its investigators. For this reason a significant number of instruments for evalauting insight in psychotic disorders were developed. Since then many papers have been published, which has allowed for a more in depth knowledge on the subject. Therefore, in recent years, the concept of insight has been developed in an attempt to clarify its compexity. A once dichotomic phenomenon, described in terms of presence or absence, became considered multidimensional, which made the identification of different levels of insight and different dimensions possible. Current concepts categorize insight into five dimensions: the awareness of the patient in relation to his/her mental illness, the awareness of the patient in relation to the social consequences of his/her illness, the awareness of the need for treatment, the awareness of the symptoms and the explanation of those symptoms in relation to the illness. The lack of insight in psychiatry, in general terms, and as this phenomenon has been described, the lack of awareness of having a mental illness, represents one of the most common symptoms of schizophrenia and affects a big part of the population that suffer from this illness. It is estimated that bewteen 50 and 80 per cent of patients with schizophrenia do not believe that they are ill, which, consequently has a big impact in the process of adherence to treatment. It is still not possible, however, to identify all the factors that determine the lack of insight in schizophrenics. There are psychological, social and cultural influences that almost certainly play their role in the lack of insight registered in this pathology.Since the impact of scizophrenia is felt in many aspects of the individual’s life, its effective treatment should be directed at various levels, including the improvement of insight. One of the objectives of this study is to explore the relationship between the level of insight in psychosis and the clinical and sociodemographic variables, the psychopathology and its global functioning. As well as the clinical and sociodemographic variables, there are of course important individual components that contribute to the level of insight seen in each patient, for example, their level of inteligence, personality, culture, past experiences, memory, etc. The clinical, emotional and/or intelectual nature of the term helps us understand the difficulty that lies in its interpretation as well as in its comprehension. Therefore, the definitions attributed to the term are very different and vary according to the theoretical training of the investigator. It is intended, from this identification/understanding, to promote the quality of life of these people through the development of new findings that might enable an active cooperation. It is equally fundamental to observe their unimpaired capacities in order to enable the acquisition of new behaviour(s) that have a positive impact on the complaints, signs, symptoms, incapacity and disfunctioning seen in the patient.As the actual comprehension of the term explains what we intend to evaluate, a detailed reflection is made on the instruments and definitions that have been used the most to explore insight in psychosis.In this investigation I tried to underline and promote the importance that each subject, undergoing medical intervention, plays during his/her process of recovery and prevention of relapses. Considering the above mentioned objectives, as well as a theoretical review of the phenomenon in terms of conceptualization and investigative studies developed, this study contributed to the validation of the instrument.The insight phenomenon chosen by the “Insight Scale”, records less changes experienced in relation to the mental illness and more actual awareness and articulation of these changes. Based on a psychopedagogical approach, the insight phenomenon explored here settled on a rehabilitation, current and multidimensional perspective that would go beyond the traditional clinical dimensions. For this reason an original scale entitled “Insight Evaluation Scale and Need Identification in Psychosis Patients” is presented, as well as a psychopedagogical intervention model soon to be used with admitted patients based on the presuppositions described in this study.

Study of antiretroviral mutants in HIV patients with treatment failures and the effect of risk factors in the virological failures

INTRODUCTION: Information about HIV phenotypes of resistant to available ART and the influence of different risk factors on virological failures (VF) in Costa Rican HIV positive patients prior or during HAART is unknown. MATERIALS AND METHODS: Eighty nine samples, 72 VF and 17 basal (before treatment) were analyzed by examining resistant mutants in reverse transcriptase (RT) and protease (PT) regions using Trugene or LIPA genotyping kits. Sixty eight control patients were selected and relevant information was collected in a questionnaire. RESULTS: Poor adherence, presence of resistant mutations and number of treatment's changes were the only significant factors found (p = 0.006, 0.04 and 0.01 respectively). From 66 sequenced samples, 78%, 50% and 50% showed resistance to NRTI (nucleoside reverse transcriptase inhibitors), NNRT (non-nucleoside reverse transcriptase inhibitors) and PI (protease inhibitors), respectively. The most frequent mutations were M41L, M184V, and T215FY in RT and L62PI, L10FIRV and M36I in PT. DISCUSSION: The most important factor related to treatment response in this study was adherence to treatment. Mutations in RT were related to the treatment failure while the ones found in PT were secondary mutations which have been previously described to influence the selection of primary resistance mutations in these regions. The study reveals the urgency to detect resistant mutations in VF to be considered by physicians for selection of treatment schedule, to analyze basal HIV patients for monitoring of the spread of resistant mutations and the importance to reinforce the adherence in the patients for overall treatment outcome.

Feasibility and acceptability of an exergame intervention for schizophrenia

Objectives To evaluate the feasibility and acceptability of an exergame intervention as a tool to promote physical activity in outpatients with schizophrenia. Design Feasibility/Acceptability Study and Quasi-Experimental Trial. Method Sixteen outpatients with schizophrenia received treatment as usual and they all completed an 8-week exergame intervention using Microsoft Kinect® (20 min sessions, biweekly). Participants completed pre and post treatment assessments regarding functional mobility (Timed Up and Go Test), functional fitness performance (Senior Fitness Test), motor neurological soft signs (Brief Motor Scale), hand grip strength (digital dynamometer), static balance (force plate), speed of processing (Trail Making Test), schizophrenia-related symptoms (Positive and Negative Syndrome Scale) and functioning (Personal and Social Performance Scale). The EG group completed an acceptability questionnaire after the intervention. Results Attrition rate was 18.75% and 69.23% of the participants completed the intervention within the proposed schedule. Baseline clinical traits were not related to game performance indicators. Over 90% of the participants rated the intervention as satisfactory and interactive. Most participants (76.9%) agreed that this intervention promotes healthier lifestyles and is an acceptable alternative to perform physical activity. Repeated-measures MANOVA analyses found no significant multivariate effects for combined outcomes. Conclusion This study established the feasibility and acceptability of an exergame intervention for outpatients with schizophrenia. The intervention proved to be an appealing alternative to physical activity. Future trials should include larger sample sizes, explore patients' adherence to home-based exergames and consider greater intervention dosage (length, session duration, and/or frequency) in order to achieve potential effects.

Prevalence and genetic characterization of Cryptosporidium spp. and Cystoisospora belli in HIV-infected patients

Cryptosporidium spp. and Cystoisospora belli are monoxenic protozoa that have been recognized as the causative agents of chronic diarrhea in immunocompromised individuals, especially HIV-infected subjects. The objective of this study was to evaluate the frequency of these intestinal protozoa in HIV-positive patients in the Triângulo Mineiro region of Brazil and to correlate the presence of these infections with clinical, epidemiological and laboratory data of the patients. Oocysts were detected in stool samples of 10 (16.9%) of the 59 patients studied, while Cryptosporidium spp. were present in 10.1% (6/59) and C. belli in 6.7% (4/59). The frequency of these parasites was higher among patients with diarrheic syndrome and CD4+ T lymphocyte counts < 200 cells/mm 3 , demonstrating the opportunistic characteristic of these infections. A significant association was observed between the lack of adherence to antiretroviral therapy and the presence of Cryptosporidium spp. and/or C. belli. Parasitism with Cryptosporidium spp. was more frequent in February and April, the months following the period of high rainfall. The same was not observed for C. belli. Genetic characterization of two isolates led to the identification of Cryptosporidium parvum, one of the main species associated with the zoonotic transmission of cryptosporidiosis.

High occurrence of giardiasis in children living on a 'landless farm workers' settlement in Araras, São Paulo, Brazil

Enteric parasitosis remains an important public health problem in many areas around the world including in Brazil, and it is frequently associated with poverty and lack of sanitation facilities. Research carried out over the course of a year revealed that 96.6% (28/29) of children randomly selected from a 'landless farm workers' settlement in Araras, São Paulo, aged 4 - 15 years, presented Giardia intestinalis cysts. After referral to the neighborhood Health Office, all the children received tinidazole, given as a single dose of 50 mg/kg and 12 months later, new fecal samples were collected and analyzed. Despite the low adherence to the study, a high percentage (64.3% - 9/14) of the children remained positive for the parasite. This study showed a high positivity of giardiasis in child residents of the settlement, even after treatment; adults were not sensitized to the study and did not collected and/or deliver children fecal samples. The precarious living conditions are consistent with a high susceptibility to parasitic diseases, suggesting that the treatment of the infected individuals without identifying and eradicating the means of contamination is simply a palliative measure.

Vulvar Lichen Sclerosus: Efficacy of Photodynamic Therapy Under Conscious Sedation with Inhaled 50% Nitrous Oxide and Oxygen Mixture

Anogenital lichen sclerosus is a chronic, inflammatory, mucocutaneous disorder of significant morbidity. Common symptoms include pruritus, pain, dysuria, and dyspareunia, frequently of difficult control. Photodynamic therapy (PDT) may be an effective therapeutic option in selected cases refractory to first--‐line treatment options. However, procedure--‐related pain is a limiting factor in patient adherence to treatment. Conscious sedation and analgesia with a ready--‐to--‐use gas mixture of nitrous oxide and oxygen is useful in short--‐term procedures. It provides a rapid, effective, and short--‐lived effect, without the need for anesthesiology support. A 75--‐year--‐old woman presented with a highly symptomatic, histologically confirmed vulvar lichen sclerosus, with at least 15 years of evolution. Pain, pruritus, and dysuria were intense and disabling. Treatment with ultrapotent topical corticosteroids proved to be ineffective despite patient compliance. She was then referred for PDT. A total of 3 sessions were performed, held at a mean interval of 9 weeks, and under the analgesic and sedative effect of nitrous oxide/oxygen gas. Response to treatment was evaluated through a daily, self--‐reported pain rating scale. Dysuria remitted completely after the first PDT session. An 80% reduction in pruritus and pain was observed after the third session, and has been sustained for the past six months without further need for topical corticotherapy. Treatment sessions were well tolerated and pain-- free, with no side effects to report. PDT appears to be effective in the symptomatic treatment of vulvar lichen sclerosus. To the authors’ knowledge this is the first case reporting the use of inhaled nitrous oxide/oxygen gas mixture during PDT performed in the genital area. Its analgesic and sedative effects may increase patients’ adherence to this painful procedure. Furthermore, given its safety, it can be easily managed in outpatient clinics by trained dermatologists.

ASSOCIATION BETWEEN SMOKING, CRACK COCAINE ABUSE AND THE DISCONTINUATION OF COMBINATION ANTIRETROVIRAL THERAPY IN RECIFE, PERNAMBUCO, BRAZIL

Despite the effectiveness of combination antiretroviral therapy in the treatment of people living with HIV/AIDS (PLWHA), nonadherence to medication has become a major threat to its effectiveness. This study aimed to estimate the prevalence of self-reported irregular use of antiretroviral therapy and the factors associated with such an irregularity in PLWHA. A cross-sectional study of PLWHA who attended two referral centers in the city of Recife, in Northeastern Brazil, between June 2007 and October 2009 was carried out. The study analyzed socioeconomic factors, social service support and personal habits associated with nonadherence to antiretroviral therapy, adjusted by multivariable logistic regression analysis. The prevalence of PLWHA who reported irregular use of combination antiretroviral therapy (cART) was 25.7%. In the final multivariate model, the irregular use of cART was associated with the following variables: being aged less than 40 years (OR = 1.66, 95%-CI: 1.29-2.13), current smokers (OR = 1.76, 95%-CI: 1.31-2.37) or former smokers (OR = 1.43, 95%-CI: 1.05-1.95), and crack cocaine users (OR = 2.79, 95%-CI: 1.24-6.32). Special measures should be directed towards each of the following groups: individuals aged less than 40 years, smokers, former smokers and crack cocaine users. Measures for giving up smoking and crack cocaine should be incorporated into HIV-control programs in order to promote greater adherence to antiretroviral drugs and thus improve the quality of life and prolong life expectancy.

HEPATITIS B VACCINATION COVERAGE AND POSTVACCINATION SEROLOGIC TESTING AMONG MEDICAL STUDENTS AT A PUBLIC UNIVERSITY IN BRAZIL

The aim of this cross-sectional study was to determine the hepatitis B vaccination coverage among medical students at a public university in Rio de Janeiro, Brazil, and their compliance with the postvaccination serologic testing recommendations. Of the total of 858 students, 675 (78.7%) participated in the study. Among the participants, 48.9% (95% CI: 45.1% to 52.7%) were vaccinated against hepatitis B (received ≥ 3 doses of the vaccine), 31.6% were not (received 0, 1 or 2 doses), and 19.6% did not know their vaccination status. Hepatitis B vaccination coverage increased from 26.0% among first-year students to 70.6% among sixth-year students while the prevalence of unknown vaccination status decreased from 39.7% among first-year students to 2.4% among sixth-year students. The frequency of unvaccinated students ranged from 23.7% among fifth-year students to 34.4% among first-year students. Only 34.8% of the vaccinated students performed the anti-HBs testing after vaccination. Among these medical students, we found a low adherence to the hepatitis B vaccination and to the postvaccination serologic testing. A comprehensive hepatitis B immunization program should be offered to students at this medical school.

Conscious Sedation with Inhaled 50% Nitrous Oxide/Oxygen Premix in Photodynamic Therapy Sessions for Vulvar Lichen Sclerosus Treatment

Photodynamic therapy has been described as an effective therapeutic option in selected cases of anogenital lichen sclerosus that are refractory to first-line treatments. However, procedure-related pain is a limiting factor in patient adherence to treatment. The authors report the case of a 75-year-old woman with highly symptomatic vulvar lichen sclerosus, successfully treated with photodynamic therapy. An inhaled 50% nitrous oxide/oxygen premix was administered during sessions, producing a pain-relieving, anxiolytic, and sedative effect without loss of consciousness. This ready-to-use gas mixture may be a well-tolerated and accepted alternative to classical anesthetics in Photodynamic therapy, facilitating patients' adherence to illumination of pain-prone areas.

Caracterização da actividade física nos idosos e a sua relação com a capacidade física, em pessoas com mais de 75 anos

RESUMO: Objectivo: O presente estudo tem como objectivo caracterizar os níveis de actividade física das pessoas com mais de 75 anos e analisar a sua relação com as diferentes componentes da aptidão física. Enquadramento: A actividade física é indispensável para todos mas, os idosos é quem mais beneficia (Fischer, 2005). Actua na prevenção e na reabilitação, fortalecendo a aptidão física, e a autonomia do idoso, permitindo manter, por mais tempo, a capacidade de execução das actividades de vida diárias (Shephard, 2003). A prática de actividade física contribui por exemplo, para a prevenção de quedas, reforçando a aptidão física e o equilíbrio postural. Por outro lado, o baixo nível de aptidão física repercute-se no aumento da actividade sedentária. Os homens têm uma adesão à actividade física de 45% e as mulheres de 28% (Melo et. al., 2007). Métodos: Este é um estudo observacional, correlacional e transversal. Foram avaliados 66 participantes (média de idade de 80,11 ± 3,83 anos), não institucionalizados. O processo de amostragem foi não probabilístico acidental por conveniência. Todos os idosos deram o seu consentimento informado. A actividade física foi avaliada através do questionário do Yale Physical Activity Survey, e foi desenvolvido um diário, para uma semana-tipo, para averiguar os hábitos de actividades diárias, nas últimas quatro semanas. A aptidão física foi avaliada pela bateria de testes de Rikli e Jones (1999),nomeadamente a força, a flexibilidade, a resistência aeróbia e a agilidade e equilíbrio. Os dados foram analisados através da estatística descritiva e para averiguar as possíveis associações entre a actividade física e a aptidão física, recorreu-se á estatística inferencial. Não tendo sido verificada a normalidade da amostra com o teste kolmogorov-smirnov, foram utilizados testes não paramétricos, nomeadamente o teste U Mann – Whitney e o coeficiente de correlação de Spearman (p≤0,05). Resultados: Constatou-se que os idosos em média praticavam 480, 23 minutos por semana de actividade moderada, cerca 11,04% do seu tempo, superior ao recomendado pela literatura (>150 minutos por semana). A actividade física moderada apresentou relações positivas com a aptidão física, na força dos membros inferiores, na resistência aeróbia e na agilidade e equilíbrio. Os homens têm maior agilidade e equilíbrio (p=0,002) e força dos membros inferiores (p=0,025) que as mulheres. Os homens passam mais tempo em actividade moderada do que as mulheres. Ainda superam no gasto energético em cada actividade que praticam durante a semana. As mulheres passam mais tempo em actividade sedentária e actividade ligeira. Conclusão: Quanto mais tempo de prática de actividade física moderada melhor a força dos membros inferiores, a resistência aeróbia, a agilidade e o equilíbrio dinâmico. Recomenda-se uma reflexão sobre a possível intervenção na estruturação das actividades diárias do idoso e uma intervenção mais direccionada às idosas, na força do membro inferior, na agilidade e na resistência aeróbia.----------------------- ABSTRACT:Purpose: The present study aims to characterize the physical activity levels of people over 75 years and analyze their relationship with the different components of physical fitness. Background: Physical activity is essential for all but the elderly who are more benefit (Fischer, 2005). It works on prevention and rehabilitation, strengthening physical fitness,and independence of older people, maintaining, for longer, the ability to implement the activities of daily living (Shephard, 2003). The physical activity contributes for example, for the prevention of falls by strengthening physical fitness and postural balance. Moreover, the low level of physical fitness level is reflected in the increase of sedentary activity. Men have an adherence to physical activity of 45% and women 28% (Melo et. al, 2007) Methods: This was an observational, cross-sectional and correlational. We evaluated 66 participants (mean age 80.11 ± 3.83 years), not institutionalized. The sampling procedure was non accidental probabilistic convenience. All seniors gave their informed consent. Physical activity was assessed by questionnaire at the Yale Physical Activity Survey was developed and a diary-type for a week, to ascertain the habits of daily activities in the last four weeks. Physical fitness was assessed by the battery of tests Rikli and Jones (1999), including strength, flexibility, endurance and agility and balance. Data were analyzed using descriptive statistics and to investigate possible associations between physical activity and physical fitness, we used will inferential statistics. Not having been verified the sample normality with Kolmogorov-Smirnov test, we used non-parametric tests, including the test U Mann - Whitney and Spearman correlation coefficient (p ≤ 0.05). Results: It was found that older people on average practiced 480, 23 minutes per week of moderate activity, about 11,04% of the time, higher than recommended in the literature (> 150 minutes per week). A moderate physical activity had positive correlations with physical fitness, lower limb strength, endurance and aerobic agility and balance. Men have greater agility and balance (p = 0.002) and lower-limb strength (p = 0.025) than women. Men spend more time in moderate activity than women. Still outweigh the energy expenditure for each activity they practice during the week. Women spend more time in sedentary activity and light activity. Conclusion: The more practice time in moderate physical activity best lower-limb strength,aerobic resistance, agility and dynamic balance. It is recommended that a reflection on the possible intervention in structuring the daily activities of the elderly and a more targeted to the woman elderly, especially lower limb strength, agility and endurance.

Diabetes : percepção da doença e auto-cuidado

RESUMO - O aumento da prevalência da diabetes e a baixa adesão ao seu tratamento estão associados a um mau controlo metabólico, desenvolvimento de complicações, aumento dos custos económicos e ineficiência do sistema de saúde. De acordo com o modelo de auto-regulação, o estudo das representações da doença permite predizer os comportamentos dos doentes face a esta patologia. O objectivo do estudo é verificar a existência de relação entre a forma como os diabéticos tipo 2 percepcionam a sua doença, de acordo com o modelo de auto-regulação de Leventhal e colaboradores, e a adesão às actividades de auto-cuidado da diabetes. Consiste num estudo observacional, descritivo, analítico, do tipo transversal, a desenvolver em Cuidados de Saúde Primários. A amostra é constituída por 339 indivíduos diabéticos, de ambos os sexos, com idade igual ou superior a 20 anos e com diagnóstico de diabetes tipo 2 há mais de 6 meses. Trata-se de uma amostra probabilística, aleatória simples, seleccionada numa Unidade de Saúde Familiar (USF). A recolha de dados é realizada através do preenchimento de uma ficha de caracterização socio-demográfica e clínica, a partir do processo clínico electrónico, e através da aplicação de dois questionários de auto-preenchimento. Os resultados são analisados através do Statistical Program for Social Sciences (SPSS) – versão 17.0.
